; Draw a texture . . woo hoo!
; t0 - texture
;
; The texture coordinates need to be defined as follows:
; tc0 - texcoords
;------------------------------------------------------------------------------

; Get the color from the texture
tex t0
tex t1

mul r0.rgb, t0, c3 +		; base times modulation
mov r0.a, c3.a				; use modulation alpha (don't use texture alpha)

mad r0.rgb, t1, c2, r0		; + envmap * envmaptint (color only)

mul r0.rgb, v0, r0			; Apply lighting 
mul_x2 r0.rgb, c0, r0		; * 2 * (overbrightFactor/2)

mul r1, t0, c1				; Self illum * tint
lrp r0.rgb, t0.a, r1, r0	; Blend between self-illum + base * lighting
